lie it known that .1, 1 125201212101; H. Gloss,

resitling at horongh of Brooklyn, county lungs, one; State of lien. Zorn, :inci

5 being n. citizen of the llni 1 States, have invented. certain new fillfl useful l a ments in liiine-Cnr il hecls At,- Means llieireztcr, of which the following a full. clear, and sit. ct tlescription, such as will enable others sll in the to which it. zippertoins to make unit to use the some,

. reference being had. to the accompanying; drawings, which illustrate the form the invention. though it is to understood that the invention is not limited. to tho exact tletnils of construction and tlcscriliecl as it is obvious that modifications thereof within the scope of the claims will occur to persons skilled in the ions ients or the spokes; new, the sermon being in section as in Fig. 1; s

hearing sleeve which is inserted in the hub;

Fig.7 is an anti elevational view of saitl sleeve; anti Fig. 8 illustrates the manner of placing the sleeve in the hub for service.

The rincipelobject of the invention is to simplir r' the construction of roller nearing mine car Wheels and eliminate unnecessary parts while producing for service a strnc- 46 tore, possessing durability and. ruggedness, preferably adapted to be attached to an axle by means penetrating the wheel.

Another object of the invention is to procluoe s wheel, of the type referred to formed from a single casting with integral seats therein for hearing rollers adsptetl to cooperate with the journal of e mine car axle.

As it is sometimes necessary to remove wheels of thistype from the axle, simple Fig. 6 is on elcvationol View of the rollermeans are also provitiecl for preventing sociclentsl displacement of the rollers when the Wheel is removed.

Referring to the parts, 1 indicates a fragment of n. mine car, 2 an axle anti 3 a wheel which, in the present instance, is QlOViflBd. with :1 bob portion and '9. cl sccl outer QIKl 5.

iYii'hin the hub is bearing roller chamt which is provided at each end with an annular channel 7 to receive spindles 8 of bearing rollers 9 incl to retain said bearing rollers E in position the hub is provitled at onto" anti with an annular flange 1O defining the iner boundary of Q channel uninterrupted, W11 e at the opnosi: encl'of the hub ll terms the inner noun-fiery of the inner channel '2' and said flange 11 is intermitted at m as host shown in Fig. 5,

3.41, and. if desired, there may extencl into said inter t portion of the ilsngell, a. removable set screw 13, the purpose or incl;

. which flange is continuous, that is, it is pressed as shown in Fig 8 and inserted through the axle opening 16, will expand radially and fill the hearing roller chamber Within the wheel huh, thereby providing a. smooth and continuous bearing for the bearing rollers 9 Within the Wheel lllll).

As the 10 and 11 are cast integral with the hub 4, it is evident that one of said flanges should be discontinuous to fa cilitate the insertion of the bearing rollers 9 and. in this instance, the inner flange is internntterl, as best shown in Figs. 4 and 5. Before the set screw 1 15 positioned, the

bearing rollers may be inserted, one at etime as indicated by the ootencl (lash lines in Fig. l in which the outer end of the roller is positioned with its'spinclle 8 ithin the bearing roller chamber 6, analefter the spiniile at the outer end of said roller is thus inserted, the inner spincllo is passed through the intermittetl portion of the flange 11 and the rollers may be inserted, one t time, in this manner, heing' permitted to drop to a lower position Within the Wheel huh after being thus inserted, after which, if desired, the set screw 13, or any suitable pin or other means, may be inserted to in ly or partly close the gap between the ends of the flange 11, thus providing support for the spindle at the inner end of the hub which maycome into coincidence with the opening Ween the Wheel is removed from its axle,

To look the Wheel in position, the outer end of the hub is preferably closed and provided with an extension through which a locking bolt or pin is projected, said pin resting in an annular recess 1-1 formed in the outer end portion of the axle 2, shovvn in Fig. 1, thereby locking the Wheel upon said axle,

In its preferred form the hu is closed at its outer end and has one open 5 ner end of a diameter approximately that of the axle 2. v

Through this opening only can the rollers 9 be inserted or removed and then only when the Wheel is removed from the axle.

The bearinga'oller chamber being of greater diameter than the axle opening, and the flanges 10ll being integral with the hub, insures against accidental loss or roller retaining flanges" or l'OlltliPi'QlillllllllQ cages, common in mine car wheels, and sures the correct positioning of the roller bearing sleeves i l in the hub.

lVhat 1 claim is:

l. A roller bearing wneel formed as a single casting provided with opi iositely disposed annular channels for recei ing ends of rollers with one of the flanges forming part of one of said channels intermit ted to facilitate insertion.

2. A roller hearing wheel ada 'ed to looked upon an axle and formed as a single casting provided with oppositely disposed annular channels for receiving the ends of rollers with one of the flanges forming part of one of said channels intcrinittcd to lacilitate insertion.

3. A roller bearing wheel formed as a single casting provided with oppositely disposed annular channels for receiving the ends of rollers with one of the flanges forming part of one of said channels intcrmitted to facilitate insertion of rollers therein, and with an extension at one end of its huh portion adapted to receive therein a pin to attach the Wheel to an axle.

l. in combination in a roller hearing Wheel. a cast metal huh formed with flanged roller channels cast Within said huh at predetermined distances apart, the flanges of said channels being spaced from the inner face or the hub andiormiug supports for hearing rollers and a single set of rollers lapping said flanges.

5. In a vhcel, cast metal huh formed with an integral annular roller retaining channel in each end, a Wall of one of said channels being intcrmit-ted to facilitate insertion of hearing rollers, andhearing rollers extending longitudinally of said hulol 6. In a roller bearing Wheel, a cast metal huh having a bcaring-roller-poclret of homogeneous metal provided with one discontinuous flange adapted to facilitate the insertion of hearing rollers in said pocket.

7. A roller-retaining mine car Wheel formed from a single casting including a roller-retaining-ilange Within each end of its huh, one of said flanges being discontinnous.

8. A roller-retaining mine car Wheel formed from single casting including a continuous roller-retaining flange at one end and a intermitted roller-retainin flange at the other end of its huh.

9. A roller-hearing Wheel comprising a cast metal huo portion with a homogeneous internally disposed roller-boaring-retaining flange near each end and one of said flanges being intermitted to facilitate insertion of bearing rollers.

10. A roller bearing Wheel formed as a single casting PlOVlClGCl with oppositely disposed annular channels for receiving the ends of rollers with hut one of the flanges forming part of one of said channels intermitted to facilitate insertion or" said rollers and a roller hearing sleeve held in position by said channels.

11. A roller bearing Wheel adapted to he lOCkQCl upon axle and formed as asingle casting provided with oppositely disposed integral annular flanged channels for receiving the ends of rollers, and a roller hearing sleeve held in position in said Wheel by said channels.

12. In combination, a cast metal hub formed with an integral flange at each end spaced from the inner face of said hub and forming supports for hearing rollers, a roller hearing sleeve held in said hub by said flanges, and a single set of rollers lapping said flanges.
